Hey man,
I started like anyone else... With a tube reel to reel recorder that I got from someone selling house stuff on the street. It was a kick ass little tape machine, way older than me.
I recorded everything I could possibly record with that thing. My dad played drums in a band so there were a lot of instruments around.
Like bass and guitar and drums and a keyboard like a Rhodes or wurly type thing.
I would record my little sister reading stupid radio play type things and edit them.. I was splicing together crazy stories when I was 9!
Nothing digital existed then.... I am in my forties and everything changed like crazy in my lifetime.
I never went to recording school. I just recorded things all the time, my whole life. That's the only way to get good at it,really.
